Bizarrely in a game where a keeper coughs up six, it was impossible to point the finger at Gordon for any of them.

His all-round handling was solid, his kicking consistent and he said: “I don’t feel I had a bad game.

“I’m not happy with the scoreline but these things happen. My decisions were sound and that’s what I am looking for.

“Our luck was just out. Sometimes you get days like that. You can’t get in the way of anything and even when you do, like the save I made for their second that hit off Filip Twardzik’s knee and went straight back to their player, it still ends up in the back of the net.”

With Deila and most of Celtic’s first team squad back in Glasgow working through issues ahead of Wednesday’s second leg with Legia Warsaw, it was left to No.2 John Collins to pan for positives. They were few and far between.

Where the boundary is between education and demoralisation for a team with eight starters aged 21 or under, four of them teenagers, and a bench barely beyond puberty, up against a Spurs squad packed with power, pace and more than £100m-worth of Premier League class is up for debate.

The only thing most of them will have learned is that they’re even further away from that level than they dreamed.

One exception was Liam Henderson, a stand-out in midfield who always seems to play with his head up and his wits about him.

Spurs were privately angry at Celtic sending such a poor side for what they had planned as a testing workout.

It’s understood the game’s Estonian organisers were also less than impressed. Not that that’s Deila’s problem. His decision to drill his players rather than send them on another pointless flight for a friendly shows he has his priorities right. Whoever sanctioned the game during Champions League qualifiers probably can’t say the same.

Spurs looked a cut above. Harry Kane and Roberto Soldado had them two up in 13 minutes and despite 18-year-old Jamie Lindsay pulling one back, Spurs restored their lead through Lewis Holtby.

Mauricio Pochettino made six changes at the break, the likes of Emmanuel Adebayor, Aaron Lennon and Christian Eriksen getting a run. But Erik Lamela made the biggest impression, his run and 20-yard shot nestling beyond Gordon after a wicked deflection.

The Nigerian, sent off in the disastrous defeat by Legia, took Adebayor out on the edge of the box with a challenge that earned him a yellow but in most games would have been a red. Eriksen hit the free-kick into the top corner.

With a minute left, Ambrose then gave away a penalty with a trip on Danny Rose which Adebayor despatched.

And he blew one final gasket with another challenge on the Togo striker which forced Finnish ref Antti Munnukka to delve into his pocket for a second time, Ambrose’s second red in four days.
